damn..... oh well. It appears that UT3 isn't entirely physx based
The 4850 will definitely be bottlenecked methinks, especially since my mobo won't allow oc past 2.02ghz (Unless it's the powersupply that holds me back.)
EDIT: For future proofing: The games I plan on getting would be the optimized Crysis sequel, Far Cry 2, and UT3 then. UT3 shouldn't be a problem, but far cry 2 and crysis are demanding. I would be satisfied with medium settings and a few high ones on the other games.
